Question
What is the difference between a soap and a detergent? How do they work? What source should be used to make a softer, more soluble soap? What happens when chlorosulfonic acid comes into contact with water? What are some possible fat sources used to synthesize soap? What is the structure of Para Red? How is it synthesized? Be able to draw this reaction. Describe the ingrain, direct, and disperse dying processes. Which type did you use in this experiment? What structural features affect the colors of dyes?Explanation / Answer
(1) Difference between soap and detergent:
Soap: Sodium or potassium salt of higher fatty acid is known as soap.
It is represented by RCOO-Na+
Ex: Sodium Stearate - C17H35COO-Na+
* It readily gives lathe in soft water but does not give any lather in hard water.
Detergent: Sodium salts of sulphonated long chain alcohols or hydrocarbons are called anionic detergents.
Quaternary ammonium salts of amines with acetates, chlorides or bromides as anions are known as cationic detegents.
Neutral detergnets are also there.
These have similar properties as soap.
They give lather with both soft and hard water.
